DRAW-BAR AND BUMPER.

SPECIFICATION forming part of Letters Patent No. 369,734, datedSeptember 13, 1887. Application filed April 6, 1887. Serial No. 233.844.(X0 model.)

To aZZ whom it may concern.-

Be it known that I, FRANCIS PE'IELER, a citi zen of the United States,residing at Minneap0lis, in the county of Hennepin and State ofMinnesota, have invented certain new and useful Improvements inDraw-Bars and Bumpers, of which the following is a specification,reference being had therein to the accompanying drawings.

Figure 1 is a plan and Fig. 2 is a side View of the draw-bar and bumper,the latter view also being in partial section.

A castiron case or bumper, A, is attached by four strong bolts, a aa a,on top and near the ends ofthe center longitudinal timber, B,ofthetruck-frame. This timber B is here stiffened by two side pieces, G C,bolted to same. Two rectangular gains, b b; across B and the sidestiffening-pieces, 0, receive ribs 0 0, formed across bottom of castingA. These ribs, in connection with the bolts a a a a, transfer the strainof motion or stopping from A to B.

The draw-bar D slips into the end of casting A. The inner end of thedraw-bar D has a hole, through which passes a large bolt, E. This boltEhas a T-shaped head, and the drawbar D pulls against the head of saidbolt E. A nut on the other end of said bolt E bears against a largeandthiek washer, F. There is also another similar washer F, and betweenthese two washers F F a double spiral spring, d, acts and reacts, beingcoiled around the bolt E. The washers F F bear against interior andopposite surfaces in the casting A, and thus motion is transferred fromD to A in either direction. A lip, e, projectlng downward from D, andbraced by two knee-brackets, f, prevents the draw-bar D from ever goinginto the casting A too far, as then 6 comes into direct contact withtimber B. This also prevents undue compression of the spring d.

G is the hole for the coupling-pin.

h is a hole in the timber B, and serves to allow the escape of any dirtthat may enter be tween the draw-bar D and the case A. This draw-bararid bumper may be applied to any kind of carsfibutas here drawn issupposed to be applied to a dumping car.

I am aware that the springs d and the washers F F in a ear-coupling arenot new, and do not claim them as such; but,

\Vhat I do desire to claim and secure by Letters Patent of the UnitedStates is as follows:

In a draw-bar and bumper for construction or other cars, the case N,resting on top of cen-' ter longitudinal timber, B, of truck-frame, all

substantially as described.

In testimony whereof I do affix mysignature in presence of twowitnesses.
